The Cisco 1700, 2600, and 3600 Series Routers support the Asymmetric
Digital Subscriber Line (ADSL) WAN Interface Card (WIC). All three platforms
are configured essentially the same, but there are differences in hardware and
in the Cisco IOS® Software release required for each one. Throughout this
document the Cisco 1700/2600/3600 will be called the "Cisco ADSL WIC."

This sample configuration shows a Cisco ADSL WIC that is connected to a
Cisco 6130 Digital Subscriber Line Access Multiplexer (DSLAM), terminating on a
Cisco 6400 Universal Access Concentrator (UAC).

Bridged IP packets received on an ATM interface configured in
route-bridged mode are routed via the IP header. The interfaces take advantage
of the characteristics of a stub LAN topology commonly used for DSL access and
offer increased performance and flexibility over IRB.

Cisco IOS Software Release 12.1(3)XJ or later (Plus versions or ADSL
feature set only) on the Cisco 1700. The ADSL feature set is identified by "y7"
in the image name; for example, c1700-sy7-mz.121-3.XJ.bin.

When you download the image for the Cisco 1700, make sure you select
the image name of 1700. Do not download a 1720 or a 1750 image; the features
will not support the ADSL WIC.
